The product of 0.1400 × 6.02 × 1023 will have how many significant figures?

3

Step-by-step explanation:

We are given that an expression

We have to find the number of significant figures in the  product .

In 0.1400 , there are 4 significant figures

In , there are three significant figures

In multiplication, we have to precise the final answer to least significant figures.

Therefore, the final answer=

Hence, three significant figures in the product.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
